Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56278, here are decompositions:

11 + 56267 = 56278
29 + 56249 = 56278
41 + 56237 = 56278
71 + 56207 = 56278
107 + 56171 = 56278
179 + 56099 = 56278
191 + 56087 = 56278
197 + 56081 = 56278

Showing the first eight; more decompositions exist.
